PROTECTION GRADE (SENSORS) IP55
CONFORMS TO THE SAFETY DIRECTIVES 12978 IN CATEGORY 3 OF
EN13849-1 AND TYPE 2 OF EN61496-2

CDR 892C3 CDR 892C3-2 Dual-beam multiplex infrared barrier.
FTR 893C3 Single-beam infrared barrier.
CDR 893 CDR891-2 Single-beam infrared barrier mounted on a rail guide DIN46277.
Suitable for the protection of passageways or spaces which are equipped with automatic installations such as
lifts and automatic doors or where you wish to detect or count the passage of people or things while using the
least possible space.
The infrared barriers with mini sensors are ideal for installations that need to be discreet but at the same time
require the passageway to be safely and reliably protected.
The electronic circuit respects the most up to date standards and regulations and conforms to the standard 3
of the EN 13849-1 (update of the EN954-1).
The necessity of guaranteeing greater ambient noise immunity has led to the evolution of both the transmitter
and receiver cards. The system is based on the criteria “resistance to single failure” that guarantees the
maintenance of safety in case of electrical problems.
The management of both the transmitter part as well as the receiver part is carried out by means of a microcontroller,
giving the advantage of greater precision when generating the impulses transmitted via infrared that
are modulated using a digital protocol thus eliminating the risk of blackout spots.

Technical description CDR891-2 PHOTOCELLS

Infrared transmission by means of digital modulation of the carrier signal.
Possibility to adjust the power of the projector by setting a jumper to one of the three available levels depending
on the range that needs to be covered.
Double relays on the receiver with digital control increase the security and safety level of the output part (the
part that furnishes the at rest/alarm signal).
Jumper for selecting the output contact mode (potential free, N.C. or resistance 8,2kΩ contacts).
Jumper for selecting the number of active beams (only in the dual beam model).
